Not sure, but it may be because of a wrong version of MSXML - it has to be MSXML 4.0 SP2, not anything newer.

It seems you are trying to install in a 64 bit environment.

Generally you have to be aware that MC15 is not certified for Win7 or Win8 (which does not mean that it will not worl under those OSs).

In this thread http://communities.ptc.com/message/253630#253630

Richard mentions that the very first release F000 is known for problems with Win7 and Vladimir reminds on the necessary components which have to be installed before the installation of MC15.

Hi,

What OS Windows are you using? And maybe this will help: http://answers.microsoft.com/en-us/windows/forum/windows_8-windows_update/after-update-messages-error-status-0xc000012f/8f0b494d-e629-43c4-8d74-82bf99e59b95
